SAFETY RAZOR.

Application mea 'June 25, 1921. serial no. 480,363.

T 0 aZZ'wLOm t may concern:

Be it known thatl I, IGNATZ l?. BLUEMEL,

"a citizen of the United States, and resident of Chicago, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements in a Safety Razor, of which the following is a specification.

My invention relates to razors and particularly'to Va'novel safety razor having provisions for adjustment.

One of the objectsV of my invention is to provide a safety razor adapted to accommodate a blade of well known form and which shall possess the characteristics of adjustability so far as the cutting edge of the blade is concerned.

The desired result is secured by providing means on the support or comb, adapted to engage the rear edge ofthe blade whereby to force the vsame forwardly. The movement is secured by providing a pair of bellcranks on the lower surface of the support, the bell-cranks being actuated by a cam rotatably mounted adjacent to and held in adjusted position by the stem or handle of the razor.

The blade is held in position on the support by means of a pivoted clamp, a spring serving to retain the clamp in proper holding position.

The invention will be more readily understood by reference to the accompanying drawings in which Figure 1 is a plan view of the end of the safety razor constructed in accordance with my invention;

Figure 2 is areverse View with the shank shown in section;

Figure 3 1s a sectional view somewhat enlarged on the line 3-3 of Figure 1;

Figure l1 is a sectional view on the line 1 -4 of Figure 1;

Figure 5 is a sectional view further enlarged on the line 5 5 of Figure 1; and

Figure 6 is a perspective view of one of the bell-cranks employed for adjusting the position of the blade.

In the drawings it will be seen that I provide a support or comb 10 havin the usual teeth 11 on one edge thereof. ivoted to a pair of projecting ears 12 on the support is a clamp having a curved blade-engaging portion 13 and a finger-engaging portion 14. A portion of metal 15 is struck out from the metal of the clamp and is bent into the position shown in Figure 5 so that it overlies a cross-pin 16 and engages beneath the support. The clamp being composed of spring metal, the portion which is struck out therefrom serves in lieu of 'a separate spring forA retaining theclamp in proper position.

At the back of the support I provide the upwardly projecting flanges 17 which act as stops to define the extent of rearwardy movement of the blade, indicated at 18.

Similar flanges 19 are provided at the sides of the supports for limiting lateral movement of the blade.

The stem or finger grip 2O is provided with a reduced and threaded portion 2lv which engages a suitably threaded opening in the support. Mounted on the reduced portion 21 is a cam member 22, the cam being best shown in Figure 2. 1When the stem 20 is rotated to the left, that is when it is unscrewed, the cam member may freely rotate but normally is held firmly in position by advancing the stem to a tightly screwed position.

Adapted to be engaged by the cam 22 are bell-cranks 23, 24C, pivoted at 25, 26, to the support and having a laterally bent portion 27 as best shown in Figure 6. This portion extends through a notch 28 in the support and lies behind the rear edge of the blade as best shown in Figure 4.

vAs best shown in Figure 2 the arms may be operated on their pivots by turning the cam member and the blade may be advanced or moved to a desired retracted position thus providing a longer or shorter cutting edge of the blade as desired.

Obviously the exact form and arrangement of parts is not essential and modifications may be made in construction shown without departure from the spirit of my invention. f

I claim:

1. In a safety razor, the combination of a support for a blade, a cam mounted beneath said support, a pair of arms actuated by said cam and adapted to engage the rear edge of a blade held on said support, and means for locking said cam in adjust-ed position.

2. In a safety razor, the combination of a comb, a spring clamp for retaining a blade thereon, a pair of arms pivoted to said comb, each of said arms having a portion adapted to engage said blade, a cam adapted to engage said arms and to force said blade forwardly, a stem and means on the stem for holding said cam in an adjusted position.

3. In a safety razor, the combination of a support, a spring Clamp pivoted to said support and adapted to retain a bladey thereon, means at the rear side and ends of said support for retaining said blade against movement in three directions, a pair of belloranks pivoted to said support and each having a portion projecting into the plane of saidblade, a Cam adapted to engage said bell-cranks, and a stem adapted lto engage said cam, and to hold the same in adjusted position.

I 4. In a safety razor, the combination of a comb, a spring clamp for retaining a blade thereon, means on said comb for preventing lateral movementof the blade, a pair of support, a pair of arms adapted to engage a blade and to move the same outwardly in right lines, a stem threaded intol saidy support, and a cam freely rotatable on'said stem and adapted to engage said arms to vmove the same to an adjusted position.
